" Yb all whom it may comet:

' useful Improvements in Be it known that I, CONRAD ESPING, a citizen of the United States, residing atMoline, in the county of Rock Island and State of Illinois,have' invented certain new and Beet-Pulling Machines, of which the following is a specification, reference being hadtherein to the accompanying drawing, being a division of original application filed May15, 1917:, Serial This invention relates to'beet pulling machines of the type embodying a wheeled frame equipped with beet pulling elements, which, in the travel of the machine, act beneath the surface of the soil and, engaging. the beet roots, automatically lift the same as the machine advances; and the invention consists of various improvements in the form, construction and mounting of the beet pulling elements, which improvements will be fully described in the specification to follow, and the novel features of which will be set forth in the appended claims,

In the accompanying drawings: p U Figure l is a top plan view of a beet pulling machine having my invention embodied. therein. V

Fig. 2 is a side elevation of the same. 1

Fig. 3' is a transverse sectional elevation of the same as viewed from the front. I

Fig. 4 is a transverse sectional elevation through the beet pulling elements on the line 4% of Fig. 2.

Fig. 5 is a one ofthe beet pulling elements separated from each other; a

Referring to the drawings:

1 indicates the machine frame, in the present instance of horizontal rectangular open form and comprising fore-andaft extending parallel side frame bars 2, a front frame bar 3 connecting the forward ends of" the frame bars 2, and a rear. frame'bar 4 connecting the rear ends of the frame bars 2. At its rear the frame is supported by two ground wheels 5 and at its front by two caster or guide wheels 6, this arrangement producing a wheeled frame on which are mounted beet pulling elements 7 with'which the present invention is particularly concerned.

These beet pulling elements, of which there are two as usual, are fixed to the lower perspective view of the parts of ads of standards 8 which extend upwardly at a rearward inclination and diverge toward their upper endswhere they are rigidly red to-the side bars 2 of the frame near the'rear ends of the same. The standards are flat, are disposed edgewisein a fore-andaft direction, and are adapted to be adjust- .ed to and from each other so as to vary the space between the pulling elements to adapt the latter for operation on different sized beet roots. The adjustment of the standards is effected by means of adjustingdevices, in the present instance in the form of upright rods 9, the lower ends of which are bolted or otherwise secured to the inner sides of the respective standards'asat 10, and the upper ends of which are threaded and extend through inwardly extending horizontal brackets 11 fixed respectively to the side bars of the frame, confining nuts 12 and'13 being screwed on the threaded ends of the rods and engaging respectively against the opposite sides of the brackets. these nuts the adjusting rods may be shifted endwise in the brackets and caused to either pull the standards toward each other or spread them apart, according to the direction of movementof'the nuts, withthe result that the pulling elements on the lower ends of the standards will be correspondingly adjusted to .vary the space between them. The action of these adjusting rods is to spring the standards to or from each other, which insures the fixed, firm and rigid support of thestandards in their different positions and avoids any possibility of looseness or accidentaldisplacement which would be apt to occur were the standards pivoted or mounted. to rock to effect their-adjustments. 7

As shown more particula-rly'in Figs. 1, i and 5, the pulling elements 7 are in the form of horizontally disposed plates fixedly connected about midway of their ends, to

the lower ends of the standards so that they will extend both in front and in rear of the same. As these plates are identical in form, and construction. a description of one will suffice. Each plate comprises a vertical portion 7 which is secured flatly to the inner side of the inturned lower end 8 of its standard, from which point the lower edge of the plate extends forwardly in a substantially straight line '2' to its forward f', Patented Dec. 2, 1919.

extremity. The lower edge extends rearwardly from the central portion 7 in an upward curve as at 7 for a short distance .and then extends to the rear extremity of the plate in a horizontal line 7 which is at, a higher level than the line 7". The upper edge of the rear portion of the plate is curved laterally outwardly,--thereby forming a rounded overhanging flange 7?, the

outer edge of which extends at an inclination toward the front of the plate and termlnates at the vertical central portion 7.

From this point to the front end of the plate, the upper edge curves downwardly as at F. The plates of this specific form are applied'to the lower ends of the standard so that their inner adjacent faces or rearward direction, the space between the plates belng therefore widest at the front and gradually contract ng toward the rear so as to present a passage or space between them of gradually decreasing width, and

.the upper edges of the plates incline gener-' ally upwardly in a rearward direction. As

a result of the formation and the relative beet root and thereby prevent injury to, the

same.

H. i In order toprevent wear on the forward- -edges of the standards above the pulling elements, at the points where in the action of the machine the standards pass through the round wear lates 9 are a i lied as shown more particularly'inFigs. 2, 3 and 4:.

These plates are of fiat form and slotted in their rear edges as at, 9 to receive the forward edges of the standards, and are fastened to the standards by means of a fastening bolt 9 passing through ears 9 proof the jecting through the edge of the standards between them, the lower ends of the wear plates being extended inwardly so as to overlie the upper edges of the pulling elements as shown in Fig. '51

in the foregoing description and accompanying drawmgs l have set forth my invention in the particular form'and embodi 11161? as to the details of the construction thereof which in practice I prefer to adopt and which has been found to answer'toa satisfactory degree the ends aimed at. It

will be manifest that various changes in the construction such as would suggest themselves to the skilled mechanic may be made without-departing from the limits of my invention; and further it will be understood rearwardly from the plate and that the invention is not limited to any par- 7 ticular form or construction of the parts except in so far as such limitations arespecified in the claims. I i

Having thus described my invention, what I: claim is; 1

1. Abeet pulling element for a beet pulling; machine, said element comprising a plate having, an. upright portion inclined at its upper edge downwardly toward the front, and provided in rear'of said, inclined portion with a curvec rfiange projecting laterally outwardly. from the upper edge of the plate.

2. In abeet pulling machine, the combination of beet pulling elements comprising opposing plates having upright faces pre sented toward, each other between whirhthe beet root isreceived, and having rounded surfaces on the upper edges of said plates;

to engage the beet.

3. In a beet pulling machine, thec'ombi nation of pulling elements comprising opposing plates converging rearwardly toward each other and each provided with an upoutwardly curved flange, the outer edge of which flange extends at an inclination 'toward the front of. the plate and terminates at the upright port-ion thereof, and the edge of the plate at the front being inclined downwardly and forwardly. i t

In testimony whereof, I have afli'xed my signature heret'oj Q 4 CONRAD ESPING.
